A script to raise the resident ratio
Note: This script does its work by looking at the vBuckets on the node that it is run from. In other words if you want to get all keys, then you have to run the script on each node of the cluster. You should be able to do them in parallel.
How to use:
sudo yum install git
git clone https://github.com/couchbasebrian/raiseResidentRatio.git
cd raiseResidentRatio
vi raiseResidentRatio.sh // edit the name of the bucket, by default it is "default"
sudo ./raiseResidentRatio.sh
Sample output
$ sudo ./raiseResidentRatio.sh
This is ./raiseResidentRatio.sh running at Wed Apr 27 19:07:43 UTC 2016 on node1-cb303-centos6.vagrants

I looked at 1024 vbucket files in /opt/couchbase/var/lib/couchbase/data/default, with 0 errors
Grep went okay, the raw ids count is 41
Trimming a list of 41 ids with sed
There are 41 trimmed ids
I attempted 41 gets and there were 0 errors.
Done. Error log can be found in /tmp/foo/rrr-errors.log
